I brought some Logitech x540 speakers home with me to Australia (240V outlets) from the States (110V) and plugged them in before realising that I should have plugged them in through a transformer first. I heard a buzz then nothing and now even with the right transformer they won't turn on.
I took it apart to see if I could just replace the fuse but after taking the thing apart the fuse appears to be intact.
Nothing appears to be burnt out or anything so i can't see what is going wrong. Could the internal transformer be blown?
It would be great if someone could give me some assistance! :)
Re: Suspected blown fuse somewhere but no sign of it
Am sure that the internal transformer is gone, You would have powered your speaker with a step up/step down transformer, you need to see a technician around you that can help you out, you need to replace a 220V-230V transformer in the speaker since your country requires that.

I don't know your exact model of TV so I can't be specific. I do know you need to hook up to audio output not input. Some TV's have audio output and some don't or you might have digital audio output which might not be compatible with your logitech speakers. If nothing else if you have a headphone plug in you might be able to hook up that way.
You would need to rewind the coils.Do not try to do it by yourself if you have no idea what you are up-to...this time it was transformer next time it could it could be your circuit.Take it to a professional,the charges won't be much. Good Luck.
Hey i am also from india. Every speaker unit has a built in fuse unit which protects it from the over voltage. just replace that with a new fuse of same rating. if you are not sure of what rating the fuse is, consult with the electrical shops. and then ask them to give a 240v to 110 or 120v AC to AC dimmer. just use this with your speakers and they will run with no problem. but if it is a serious damage inside then you need to take it to a service center.
the suggestion to my guess is right,audio input to the line out jack on tv for it too work you would need the head phone jack witch would go in to auido in an split to RCA Audio out (TV) Witch meaning, adapter to convert regular RCA type (red/white) connectors to a standard mini plug (Headphone type) Hope it Works
